CLAY-DISINTEGRATING MILL.

SPECIFICATION forming part of Letters Patent N 0. 452,896, dated May 26,1891. Application filed July 21, 1890. Serial No. 359,356. (No model.)

To all whom it hwy concern:

Be it known that I, HORACE B. CAMP, a citizen of the United States,residing at Cuyahoga Falls, in the county of Summit and State of Ohio,have invented a certain new and useful Improvement in Clay-TemperingMachines, of which the following is a specification.

The object and purpose of my invention is to produce an improved machinefor tempering clay preparatory to its use in brick, tile, sewer-pipe, orother forming or molding machines, and is ancillary and germane to amachine for disintegrating clay, for which I have made application forLetters Patent under date of May 5, 1890, Serial No. 350,601.

To this object and purpose my invention consists in certain peculiar andnovel c011- struction, combination, and arrangement of parts hereinafterdescribed, and then specifically pointed out in the claims, referencebeing had to the accompanying drawings, forming a part of thisspecification.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure l is an end elevation of a machine embodyingmy invention, and Fig. 2 a central vertical longitudinal section of thesame at the line so as of Fig. 1.

Referring to the drawings, A is a frame, preferably of wood beams, asshown, and securely fastened to a floor B by bolts C, as shown, or byother equivalent or preferred device. J ournaled in suitable bearings onthis frame are flanged rollers E, preferably mounted on parallel shaftsD. Resting and revolubly mounted on the rollersE is a drum F, consistingof two oppositely-disposed annular disks G G, preferably of cast metal,united bya shell or hoop 11, preferably of sheet metal, bolted to innerannular flanges extending from said disks. This drum, as shown, isrevolved by means of a belt J, which runs on an annular flange I,attached to the disk G, and is driven from any convenient pulley; butthis method of revolving the drum is not essential, as it may beaccomplished by other means, as hereinafter described. In opposite endopenings of this drum are heads or covers K K, respectively attached tothe frame Aby brackets or straps L L, which covers serve to prevent theesloosely either by these brackets orsome similar device, so that theymay yield slightly to inequalities in the shape of the inner peripheryof the disks G G or the motion of the drum in its revolutions.

.Iournaled in suitable bearings in the frame A and passing throughopenings in the covers K K is a shaft M, which bears outside of the druma pulley P and inside the drum a solid cylinder N, inserted in andprojecting from which are radial pins 11, and which, for the purpose ofthis application, may be denominated the mixer.

The shaft M is mounted eccentric to and parallel with the axis of thedrum F, and when the cylinder N bears the relation to the drum F shownis preferably in the same horizontal plane. By this arrangement themoistened clay as it is carried upward on the inner periphery of thedrum F is encountered by the pins '12 and thrown backward, ashereinafter described.

A belt Q drives the pulley P from any con venient power in a directionopposite to the motion of the drum. Suspended by the frame A below thedrum F is a hopper S, terminating at the bottom in a delivery-spout,through which the tempered clay is discharged.

In the periphery of the drum F are a series of openings T, disposed atintervals lengthwise of and about the drum, each closed with a hingeddoor U, the hinges of the doors being in the direction of the revolutionof the drum. These doors are fastened when desired by latches (notshown) of any desired or approved pattern, and when these latches arereleased the descending doors, when about the horizontal plane of theaxis of the drum, will open by gravitation, while the opposite ascendingdoors will close. Through the cover K is a pipe V, connected with awater-supply under pressure, and terminating in a rose or spraynozzle,the object and purpose of which is to sprinkle and moisten the clay inthe drum and which pipe is provided with a gate by which the supply ofwater may be regulated. This rose may be placed at any desired point inthe drum, and in some cases it will be found advantageous to provide twoor more or to substitute a finely-perforated pipe running across thedrum.

In operation the doors U are closed and latched, and the drum F andmixer N are revolved in opposite directions, the former slowly and thelatter rapidly, their relative degrees of speed will be determined bythe character, condition, and requirement of the clay to be tempered.The clay, preferably disintegrated or ground, is then fed into the drumthrough the door R and moistened by water from the pi peV until asufficient charge has been placed in the drum and properly moistened.During this process the moistened clay is continually carried up on theinside periphery of the drum until it encounters the pins 02, by whichit is violently stirred and thrown back upon the coming mass, and thisis continued until it is properly tempered and perfectly homogeneous,when the latches of the doors U are released and the tempered clay fallsthrough the openings T into the hopper S.

As hereinbefore suggested, I do not attempt in this application to givethe precise relative proportions of the different parts or their exactpositions, as these must of necessity differ with the differentrequirements of the machine and as experience may determine to bebest-as, for instance, the cylinder N may be increased in size orreduced to the shaft M, and as a consequence the pins n will differ inlength and mode of attachment, as they may in shape, and the flange Iand belt J may be omitted and the power. applied directly to the pulleyP, and thence by any Wellknown device, as sprocket wheels and chain, tothe rollers E, without departing from my invention, which I claim tobe 1. A clay-tempering machine consisting of a revolubly-mountedhorizontal drum having peri phcral discharge-doors, a mixing-cylinderhaving radial pins revolubly mounted inside of, parallel with, andaxially eccentric to said drum in bearings outside thereof, and means,as belts, for independently simultaneously revolving said drum andmixing-cylinder in opposite directions with different degrees of speed,substantially as shown and described. 2. In a clay-tempering machine,the combination, with a revolving drum having peripheraldischarge-doors, and a mixing-cylinder having radial pins mounted torevolve inside of said drum axially eccentric thereto, of coversarranged to close the end openings of said drum, one whereof is providedwith a feedingdoor, and means, as belts, for simultaneously revolvingsaid drum and mixing-cylinder in opposite directions with differentdegrees of I speed, substantially as shown and described.

3. In a clay-tempering machine, the combination, with a revolublymounted horizontal drum, and a mixing-cylinder having radial pinsmounted to revolve inside of said drum in bearings outside thereof, of awater-supply pipe extending into said drum and provided with a spray-nozzle or rose to moisten the clay in the process of mixing,substantially as shown and described.

4. A clay-tempering machine embodying the following elements: asupporting-frame, a drum having end openings revolubly mounted thereonand provided with dis charge-gates, a mixer having radial pins revolublymounted in and axially eccentric to said drum, covers for the endopenings of said drum, one whereof is provided with a feeding-door, ahopper to receive the clay from said discharge-gates, and a water-supplypipe arranged to moisten the clay within the drum, all constructed andarranged substantially as shown, and for the purpose specified.

In testimony that I claim the above I hereunto set my hand.
